引入maven依赖：

<dependency>
           <groupId>org.apache.commons</groupId>
           <artifactId>commons-compress</artifactId>
           <version>1.9</version>
       </dependency>

打包

将path文件夹下所有文件都打包到out文件中。

/**
    * Do zip pack.
    *
    * @param path the path
    * @param out  the out
    * @throws IOException the io exception
    */
   public static void doZipPack(Path path, Path out) throws IOException {
       //zip流
       ZipArchiveOutputStream zaos = new ZipArchiveOutputStream(out.toFile());
       Files.walkFileTree(path, new SimpleFileVisitor<Path>() {
           @Override
           public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
               ZipArchiveEntry zae = new ZipArchiveEntry(file.toFile(), "/" + file.getFileName().toString());
               zaos.putArchiveEntry(zae);
               InputStream is = new FileInputStream(file.toFile());
               byte[] b = new byte[PicConstant.ONE_ZORE_TWO_FOUR * PicConstant.FIVE];
               int i;
               while ((i = is.read(b)) != -1) {
                   zaos.write(b, 0, i);
               }
               is.close();
               zaos.closeArchiveEntry();
               return FileVisitResult.CONTINUE;
           }

       });
       //关流
       zaos.finish();
       zaos.close();
   }
